Our Guide to Woods for Wooden Wedding Rings

Lignum Vitae (Guayacán)

Guaiacum officinale

Known in Nicaragua as Guayacán and recognized internationally as Lignum Vitae — Latin for "wood of life" — this is among the densest, hardest woods in the world. It was historically prized for ship propeller shaft bearings because of its extraordinary durability and natural self-lubricating oils, dense enough to sink in water. Its color ranges from deep olive to near-black, with a fine, feathered grain that takes on a quiet, glowing richness once shaped and finished.

For a ring meant to be worn every single day for life, Lignum Vitae is one of our most trusted choices — a wood that was, quite literally, named for its endurance.

Guapinol

Hymenaea courbaril

Guapinol grows throughout Central America and is known internationally by another name: Jatobá, or Brazilian Cherry, prized worldwide for flooring and fine furniture because of its remarkable hardness. Fresh-cut, the heartwood is a warm salmon-red that deepens over time into a rich russet brown, often marked with darker streaking that gives every piece its own character.

We love Guapinol for the warmth it brings to a ring — a deep, sunlit reddish-brown that pairs beautifully with both yellow and rose gold.

Nacascolo

Caesalpinia coriaria

Nacascolo is a coffee-brown hardwood with a fine, even grain, native to the Caribbean and Central and South America.

As far as we know, we are the only makers of wood wedding rings using Nacascolo wood — and it has become the cornerstone of our wood ring collection, the single most popular wood among our customers.

We typically source our Nacascolo from our own family farm in Central Nicaragua — gathering it ourselves, in small quantities, the same patient way we approach our reforestation work in the region.

Ñambaro (Cocobolo)

Dalbergia retusa

Known locally as Ñambaro, this wood is more widely recognized around the world by another name: Cocobolo, one of the most celebrated rosewoods anywhere. Nicaraguan Cocobolo in particular has a reputation among woodworkers for its vivid colour — deep reddish-brown swirled with streaks of orange, red, and black, each piece entirely its own. Its dramatic grain makes it a favorite in our stone inlay wedding bands, where the colour of the wood plays beautifully against gemstone accents.

Cocobolo is a slow-growing, increasingly rare hardwood, which is exactly why we collect it carefully and only in small quantities. Every piece we use represents a responsible, considered choice — never taken for granted.

Koa

Acacia koa

Native to the Hawaiian islands, Koa is a warm, reddish-brown hardwood prized for its rich color, glowing luster, and the way it seems to shift and shimmer slightly depending on the angle of light. It's a wood with deep cultural significance in Hawaii, traditionally used for canoes and fine craft, and it has become one of the most sought-after woods in fine jewelry and instrument making worldwide.

Koa pairs beautifully with both warm and cool metals, and we especially love it alongside turquoise, where the stone's blue-green tones bring out the depth of the wood's natural reddish-brown grain.

  

Coyol — and a Note on Ebony

Acrocomia aculeata (seed)

Coyol holds a different kind of place in our story than any other material we work with — because it's where Naturaleza began. Our very first rings, our own engagement rings, made before we ever had a formal business, were carved from coyol seeds that Marlon gathered himself. You can read more about those early days on our Our Story & Process page.

We still collect coyol ourselves, by hand, on the island of Ometepe in Nicaragua. The seed comes from the coyol palm, a tree better known throughout Central America for the sweet fermented drink made from its sap than for its use in jewelry. The extraordinarily hard endocarp surrounding the seed — the part we work with — is smooth, evenly deep black, and remarkably durable, often compared to ebony in both appearance and strength.

As far as we know, we're the only fine jewelry maker working with coyol in this way. It will always be the material closest to where we started — and you can see real examples of coyol rings we've made in our Custom Ring Gallery.

If you're drawn to ebony — the classic deep-black hardwood you may have seen elsewhere — we're happy to make that available too. But we'll always point you toward Coyol first. It's darker and richer than ebony, every bit as durable, and unlike ebony, which is widely harvested as timber from increasingly threatened forests, our coyol is a seed we gather entirely by hand, one at a time, without ever cutting down a tree. It's also simply ours — the material our very first ring was made from, and one you're unlikely to find used this way anywhere else.
